Physical activity is beneficial for pregnantwomen in lowering their risk ofdeveloping gestational diabetes. A study,reported in Epidemiology (January 2006),evaluated the association between gestationaldiabetes and "perceived exertion" inthin and overweight women. This evaluationwas accomplished, in part, by interviewingthe women on how they ratedtheir energy level during usual exercise inthe year prior to becoming pregnant.
The researchers learned that, the higherthe level of perceived exertion, thelower the risk of gestational diabetes. Thewomen who reported very strenuoususual exertion were 81% less likely todevelop pregnancy-induced diabetes. Thewomen who reported moderate usualexertion had a 59% lower risk.
